poly(3-hydroxybutyrate-co-3-hydroxyvalerate)

polymer

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate), or PHBV, is a biodegradable polyester copolymer synthesized from 3-hydroxybutyrate and 3-hydroxyvalerate monomers, belonging to the family of polyhydroxyalkanoates (PHAs). It combines the rigidity of PHB with improved flexibility and processing characteristics, making it a promising biopolymer for applications where conventional plastics would persist as environmental waste. PHBV is used in medical devices, agricultural films, packaging, and tissue engineering scaffolds, where its biodegradability and biocompatibility offer distinct advantages over petrochemical polymers, though processing limitations and cost have historically restricted broader industrial adoption.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
